A REVIEW OF STUDIES ON TARGET- AND NON-TARGET EFFECTS OF
BT MAIZE IN SOUTH AFRICA

GM Bt maize that produces Cry1Ab proteins have been planted in South Africa since 1998. The target pests of Bt maize are the lepidopterous stem borers, Busseola fusca (Noctuidae), Chilo partellus (Crambidae) and Sesamia calamistis (Noctuidae). Resistance development and possible non-target effects have been of concern since the first deployment of genetically modified (GM) crops with insecticidal properties. It is especially at the third trophic level and with important predators and parasitoids where negative effects of insecticidal proteins could have adverse effects in agro-ecosystems. Research on important non-target species was conducted in laboratory and semi-field conditions. The non-target species that were studied included organisms at the 3rd trophic level, i.e. the parasitic fly, Sturmiopsis parasitica (Tachinidae) and the Green lacewing, Chrysoperla pudica (Chrysopidae). Non-target herbivores that were evaluated were Heteronychus arator (Scarabaeidae), Somaticus angulatus (Tenebrionidae), the cutworm, Agrotis segetum (Noctuidae) and African bollworm, Helicoverpa armigera (Noctuidae). The effect of Bt maize on life history of the earthworm, Eisenia fetida (Annelida) was also studied. Results indicated that indirect exposure of predators and parasitoids at the 3rd trophic level had no adverse effect on their life-history. Results of in which life-history parameters of non-target herbivores were compared between Bt- and non-Bt maize showed that Bt maize had no major adverse effects. Minor effects were observed in longevity of some species but considering that these studies were done at very high exposure levels to the Cry1Ab protein, no adverse effects are anticipated under field conditions. Studies on the target pest, B. fusca, showed that resistance evolved against the Bt-toxin and that no fitness costs were associated with the evolution of resistance. New GM events are continuously being developed and crop varieties with multiple genes, aimed at controlling several target species, are being introduced into the country. Non-target effect studies should involve the above mentioned species as well as other organisms identified through biodiversity surveys and those that could act as surrogate species for certain functional groups.

ACCEPTANCE OF SUBMISSIONS AND ABSTRACTS
• Slots have been left in all congress sections for inclusion of relevant submitted papers.
• However, it is the policy of the Society to accept all submissions and should any submission not fit into a section, time slots will be available for papers in areas other than the listed sections. It may even be possible to group these papers according to a specific common interest.
• To facilitate delegates who will need to request funding (the Society does not provide funding), we will be able to supplyletters of acceptance of presentations as soon as abstracts have been received(these will not specify whether the presentation is oral or a poster). Authors shouldbe in contact with the organizers when such letters are required.
• You must register as a delegate and pay your registration fee to the 18th ESSA Congress by 4 June 2013in order to have the abstract of your paper submission (oral or poster)scheduled in the congress programme and to have your abstract appear in thecongress proceedings.
• Registrations later than 3 June will be allowed but due to printing deadlines, such delegates will most likely not be able to present a poster or oral presentation.
• Papers that have previously been accepted will be scratched from the programme and the relevant abstracts will be removed from the proceedings if the presenting author has not registered and paid all congress dues by 4 June 2013.
STUDENT AWARDS
• Prizes will be awarded for the best student oral presentation and best student poster.
• Should students wish to participate in this, abstracts should be clearly labeled as ‘student award entry’ upon submission.
